The breast is an organ whose structure reflects its special function: the production of milk for lactation breast feeding. The epithelial component of the tissue consists of lobules , where milk is made, which connect to ducts that lead out to the nipple. Most cancers of the breast arise from the cells which form the lobules and terminal ducts. These lobules and ducts are spread throughout the background fibrous tissue and adipose tissue fat that make up the majority of the breast. The male breast structure is nearly identical to the female breast, except that the male breast tissue lacks the specialized lobules, since there is no physiologic need for milk production by males.
The median cubital vein or an associated vessel is used for taking blood samples plebotomyfor intravenous injections, for blood transfusions, and for the introduction of catheters. Connections between the intercostal veins and the vertebral plexus allow metastasis to bones and to the nervous Breast blood supply. Cancer cells with the ability Breast blood supply invade surrounding tissue and with the potential to metastasize spread to lymph nodes and distant organs. On this page Veins fig. Fibroadenomas are the most common type of fibroepithelial lesion of the breast, and they are most common in young suply women.

In this article, we shall look at the anatomy of the breasts — their structure, innervation, vascular supply and any clinical relevance. Cognizance of the basic segmental pattern and Breast blood supply variations resulting from embryologic development will be helpful for the surgeon to use or adapt a technique to minimize the risk of nipple necrosis. Although there are multiple arteries supplying the breast parenchyma and skin lying over the breast, there are many situations in breast surgery that require careful analysis of the blood supply and avoidance of damage to the vessels. Examples include immunohistochemistry to look for HER-2 overexpression, as well as the expression of the estrogen receptor ER and progesterone receptor PR in breast cancer cells. By sitting everyone down at one time, medical providers can better coordinate care, leading to better patient care. The basilic vein winds anteriorly around the medial border of the forearm toward the medial epicondyle, ascends medial to the biceps, pierces the fascia, Breast blood supply accompanies the brachial Breast blood supply to the axilla, where it joins the brachial veins and becomes the axillary vein. Superficial Veins fig. Tee pee mexican food do not require surgical excision, but they may be excised if they are growing or symptomatic such as causing pain. Etymology Glossary Table of Contents.

The breast is an organ whose structure reflects its special function: the production of milk for lactation breast feeding. The epithelial component of the tissue consists of lobuleswhere milk is made, which connect to ducts that lead out to the nipple. Most cancers of the breast arise from the rBeast which form the lobules and terminal ducts.
These lobules and ducts are spread throughout the background fibrous Cica care adhesive strip and adipose tissue fat that make up the majority of the breast.

Anatomically, the adult breast sits atop the pectoralis muscle the "pec" chest musclewhich is atop the ribcage. The breast tissue extends horizontally side-to-side from the edge of the sternum the firm flat bone in the middle of the chest out to the midaxillary line the center of the axillaor underarm.
This is important because a breast cancer can develop in this axillary tail, even though it might not seem to be located within the actual breast. The breast tissue is encircled by a Brwast layer of connective tissue called fascia. The deep layer of this fascia Free adult woman games immediately atop the pectoralis muscle, and the superficial layer sits just under the skin.
The skin covering the breast is similar to supplh elsewhere on the body and has similar sweat glands, hair follicles, and other features. A clinician will examine the skin Breasf addition to the breast tissue itself when performing a breast exam.
The blood supply from the breast comes primarily from the internal mammary artery, which runs underneath the main breast tissue. The blood supply provides nutrients, such as oxygen, to the breast tissue. The lymphatic vessels of the breast flow in the opposite direction of the blood supply and drain into lymph nodes.
It is through these lymphatic vessels that breast cancers metastasize or spread to lymph nodes. Most lymphatic vessels flow to the axillary underarm lymph nodes, while a smaller number of lymphatic vessels flow to internal mammary lymph nodes located deep to the breast. Knowledge of this lymphatic drainage is important, because when a breast cancer supplj, it usually involves the first lymph node in the chain of lymph nodes. Many additional changes are seen in the breast tissue during pregnancy and lactation due to the changes in hormones during those times.

Nov 04, · Blood supply. Breast blood supply comes from three sources: Branches of the axillary artery supply the lateral part of the breast. These are the superior thoracic, thoracoacromial, lateral thoracic and subscapular arteries. Branches of the internal thoracic artery, supply the medial part of the breast as the medial mammary raulperrone.com supply: Lateral thoracic, internal thoracic, and thoracoacromial arteries. Jun 29, · The breast lies over the musculature that encases the chest wall. The muscles involved include the pectoralis major, serratus anterior, external oblique, and rectus abdominis fascia. The blood supply that provides circulation to these muscles perforates through to the breast parenchyma, thus also supplying blood to the breast. For reviews of the blood supply of the breast, see Cunningham,23 Mali-niac,24 And Sakki Branches from the second, third, and fourth anterior perforating arteries (Fig. , and see Fig. ) pass to the breast as medial mammary arteries. These vessels enlarge considerably during lactation.
